This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

8 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  2. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Business context

Business profile

Its market positioning is strengthened by Google Partner status and a broad portfolio of services including PPC campaigns, product comparison platforms, SEO, social media, and creative services like graphic design and programming.

Security posture

The website demonstrates a good security maturity level with HTTPS enforced and no visible exposure of sensitive data. The use of secure forms with validation and absence of vulnerable libraries are positive indicators. However, the lack of explicit security policies, incident response contacts, and security headers such as Content-Security-Policy or X-Frame-Options suggests areas for enhancement. Compliance with GDPR is evident through privacy and cookie policies, though the cookie consent mechanism could be more explicit. No vulnerabilities or malware indicators were detected in the content. The security culture appears focused on transparency and client data ownership, as stated in their cooperation philosophy. Overall, the security posture is solid but could benefit from formalized policies and technical header implementations.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish explicit security and incident response policies with dedicated contact channels to improve transparency and readiness.
  3. Introduce a clear cookie consent mechanism compliant with GDPR to ensure user consent for tracking technologies.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Consider publishing a security.txt file to facilitate responsible vulnerability disclosure and improve trust.

Technical notes

Notes

The website is built on a custom CMS platform with extensive use of modern JavaScript libraries such as Swiper.js for sliders, Typed.js for text animations, and jQuery UI for UI components. It integrates multiple analytics and tracking services including Google Analytics, Google Tag Manager, Facebook Pixel, Hotjar, and Smartlook, enabling detailed user behavior analysis and marketing optimization. Hosting is provided by Wedos, a Czech hosting provider, consistent with the domain's nameservers. The site is mobile-optimized with responsive design and good accessibility features. Performance is moderate, with asynchronous loading of scripts to improve page load times. SEO is well addressed with proper meta tags, Open Graph data, and structured JSON-LD data for organization information. Technical risks are minimal but could be further reduced by enhancing security headers and formalizing compliance mechanisms.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
